EFFECT OF AGE ON SOMEN QUALITY AND SOME MINIRALS, AND TESTOSTERONE HORMONE IN AWASSI RAMS

Abstract

The study was conducted in the laboratories of the Musayyib Technical College in cooperation with a private field for sheep breeding in Al-Mahaweel District / Babylon Governorate from September to November 2020, to study the effect of age on semen quality and some minerals, and testosterone hormone, thanks. of Awassi rams, 12 Awassi rams were used and divided into three categories. Age, the first: 1-3 years, the second: 3-5 years, and the third: over 5 years old. Blood was drawn, serum was separated, and its biochemical and hormonal components were analyzed. The results of the study showed a highly significant (p≤0.01)) for the age group greater than 5 years in zinc ion (Zn) concentration compared to other age groups. There was a significant superiority (p≤0.01) for the age group 3-5 years in calcium (Ca) concentration and testosterone level over the other age groups. A highly significant (P≤0.01) was observed for the age group 1-3 years in the concentration of iron ions (Fe) compared with other age groups. The results of the study also showed a positive, direct and highly significant correlation of (Ca) with the testosterone hormone, and a negative, inverse and highly significant correlation coefficient between (Zn) and iron. with testosterone
